It can effectively prevent wires and cables from being damaged or broken due to drilling, nailing or corrosion, thereby protecting the stable operation of the electrical system. At the same time, the conduit is also often used as a lead in house decoration, home appliance installation, and lighting installation.

[0003] The most common plastic conduit on the market is the plastic conduit; however, the existing plastic conduit is easy to reset itself after bending, which is not easy to shape, thus affecting the laying, and is easy to be crushed during laying.

[0004] Therefore, it is very necessary to invent a threading tube that can be bent significantly. Utility Model Content

[0006] Preferably, a plurality of holes are evenly distributed through the surface of the carbon steel corrugated pipe.

[0007] Preferably, a first reinforcing plate is fixedly installed inside the elastic tube, and a second reinforcing plate is fixedly installed between two adjacent elastic tubes.

[0008] Preferably, four buffer chambers are formed between the plastic inner tube, the corresponding elastic tube and the corresponding reinforcing plate 2.

[0009] Preferably, four wiring cavities are formed between the four elastic tubes, the cross bracket and the second reinforcing plate.

[0010] Compared with the prior art, the advantages of the utility model are:

[0011] The overall arrangement of the utility model can shape the threading tube after being greatly bent, thereby preventing the threading tube from being reset, thereby facilitating laying; at the same time, it can have good pressure resistance when subjected to external pressure, thereby preventing it from being crushed.

[0016] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0017] In the description of the embodiments, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0018] The utility model is further described below in conjunction with the accompanying drawings: Embodiment 1

[0019] Reference Figure 1-2A threading tube that can be bent to a large extent comprises a carbon steel corrugated tube 3, wherein: a plastic outer tube 1 is fixedly installed on the outer surface of the carbon steel corrugated tube 3, and a plastic inner tube 2 is fixedly installed on the inner surface of the carbon steel corrugated tube 3, and the plastic inner tube 2 is fixedly installed on the plastic outer tube 1, and the plastic inner tube 2 is fixedly connected to the plastic outer tube 1. By setting the plastic outer tube 1 and the plastic inner tube 2, the carbon steel corrugated tube 3 can be protected, and the corrosion resistance and wear resistance of the carbon steel corrugated tube 3 can be improved; four elastic tubes 4 are evenly fixedly installed inside the plastic inner tube 2, and a cross bracket 5 is fixedly installed between the four elastic tubes 4. By setting the four elastic tubes 4 in conjunction with the cross bracket 5, the overall strength can be improved, and when the threading tube is subjected to external pressure, it can resist and prevent the threading tube from being crushed, and the cross bracket 5 is located at the center of the plastic inner tube 2.

[0020] A plurality of holes 10 are evenly distributed through the surface of the carbon steel bellows 3. The arrangement of the holes 10 can reduce the weight of the carbon steel bellows 3. Due to the characteristics of the carbon steel bellows 3 itself, it can be bent and shaped to a large extent, so that after the threading tube is deformed, it can have good self-retention ability to prevent resetting.

[0021] A reinforcing plate 6 is fixedly installed inside the elastic tube 4. By setting the reinforcing plate 6, the strength of the elastic tube 4 can be improved. A reinforcing plate 2 7 is fixedly installed between two elastic tubes 4. By setting the reinforcing plate 2 7, the strength between the four elastic tubes 4 can be improved.

[0022] Four buffer chambers 8 are formed between the plastic inner tube 2 and the corresponding elastic tube 4 and the corresponding reinforcing plate 7. Through the setting of the four buffer chambers 8, when the threading tube is subjected to external pressure, it can have a certain deformation ability and resistance ability, thereby preventing the four wiring chambers 9 from being crushed.

[0023] Four wiring cavities 9 are formed between the four elastic tubes 4, the cross bracket 5 and the reinforcing plate 2 7. Through the provision of the four wiring cavities 9, wiring can be performed separately, thereby preventing the wiring harness from being entangled in the wiring tube, so as to facilitate later maintenance.

[0024] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
